Description of the invention (3) The shape of the cross section of the synthetic resin wire 1 can be approximately regular polygons, and when implementing the regular polygons, Can be about regular triangle or regular quadrilateral or regular pentagon. In the implementation of the second configuration, although the wide and narrow changing portion of the helical ridge line 2 is only applied to one end portion of the wire L or only to both end portions, it can be implemented to make the predetermined length portion longer than the other portions. The pitches forming the spiral thread pitch are narrower, that is, those with more strands. In the implementation of the third configuration, although the predetermined area of one end portion of the wire rod 1 or only the predetermined length portion of both end portions is used to reduce the cross-sectional area of the wire rod L, it may be implemented as a thin wire. . Furthermore, it is also possible to implement the number of twists of the thinned portion more than the number of twists of other portions.

The spiral wire L formed as described above is referred to as a "lead-through wire" in the present invention. The end face is formed into a line with a regular triangular cross-section as shown in Fig. 2. Therefore, it is assumed that it contacts the midpoints of the sides of the triangle. The large area f surrounded by the line circle is continuous with the full length of the wire L, and the large area f can bear the pressing force in the axial direction. Therefore, a wire with excellent compression resistance and excellent traction resistance can be obtained, and at the same time, the helical ridges 2 formed by the tops of the triangles 11 ... can be used to support the load of the wire coil body by point contact to reduce The contact resistance with the cable protection tube can be used as a thick wire with less resistance. In order to commercialize this, as shown in FIG. 3, at the spiral wire L = one end, it is connected by a cylindrical connection fixing member 8 to guide the connection to an electric hole such as a pipe ^ P line or a telephone line. The leading end guide fixture G of h is connected to the flexible wire y. In this way, a lead wire as a so-called commodity is completed. Side ί: The connection system such as the end fixing member is not limited to only the end of the line machine, and the two ends of the wire L may be connected. Alternatively, only the upper rigid end guide fixing member G may be directly connected to the wire L. In the case of the material 1, when the above-mentioned wire rod [is manufactured, the cross-section triangle-shaped wire 35々, 4η ^ is described above, and is given 20 times, 25 times, and 30 times per 1 meter, respectively.

The samples were also subjected to deflection tests. In this deflection test, there was no significant difference between the number of twists, the number of twists, the number of twists, and the number of twists of 25 or 30. However, it was confirmed that the number of twists increased by approximately 35 or more, especially 50 or more. Increase in scale Figures 4 to 6 show the line material of other embodiments! The shape of the end surface is shown in Figure 4 as being approximately regular quadrilateral, the figure 5 is shown as being approximately regular pentagon, and the figure 6 is shown as being approximately regular six. Therefore, ‘these line materials i are implemented into the spiral wire 6 according to the above-mentioned implementation, and one with four spiral edge lines, cicada = line and six spiral edge lines, can be obtained.

483208 V. Description of the invention (6) Constructor of diameter part C. In this way, the thinned wire portion C is formed at one end side of the wire L. As described above, it is not necessary to connect the conventional flexible wire Y at the front end of the wire l, and the front end portion can be easily bent and has the required flexibility. Flexible wire. The embodiment shown in FIG. 9 is to form one end portion of the wire l to form a thinner wire diameter than the ordinary wire diameter portion A (; and twist the number of twists per unit length of the thin warp portion It is a structure that has a larger number of twists than the ordinary wire diameter part A. With this structure, a wire that is easy to bend at the front end of the wire L and has appropriate flexibility can also be obtained. As shown in FIG. 8 and 9 The processing for locally narrowing the wire diameter as shown in the example in the figure can be performed in an independent processing process, or in a twist application process for a resin wire with a heating device, or when the wire is extended and processed. It can also be implemented by increasing the amount of extension of the required length component for each required time. The resin material of the wire is not intentionally limited, but it has less aging deterioration, excellent pressure resistance, elongation resistance, toughness and flexibility. In terms of excellent flexibility, the polyester resins described above are still preferred, but polyolefin resins such as pp and pE are also non-pneumatic resins and have the above properties, which is ideal. Illustrative examples, but the present invention is not limited to those described in the examples. Those who have the above-mentioned constituent elements described in the present invention and achieve the objects described in the present invention and have the effects described below. The range can be appropriately changed and implemented by the implementer. [Effects of the Invention]

483208 V. Description of the invention (7) As can be understood from the above, the lead wire of the first composition of the present invention is a synthetic resin wire with a polygonal shape in cross-section extended and twisted to form a spiral ridge on the outside. The structure has a wide area f surrounded by an imaginary line circle D in contact with the midpoints of the sides of the wire, and is continuous over the entire length of the wire l. It can bear the compressive and tensile forces in the axial direction. With the amount used, it is light and easy to use, and it is significantly superior to the compression resistance and traction resistance of the lead wire. Also, as described above, the lead wire of the second structure is a component that provides a wide variation in the interval of the axis of the spiral ridge in the axial direction of the spiral ridge compared to other wire portions as a part of the wire that forms a spiral ridge on the outside. Therefore, this part is formed at the end of the wire, so that the front end can be easily bent along the bend of the electric protection tube without having to connect other members to the front end, and the wire with the required rewindability can be avoided. In the case where the connecting and fixing member of the flexible wire becomes resistance in the piping, it has the effect of enabling smooth operation. As described above, the lead wire of the third structure is a portion of the wire that forms a spiral ridge line on the outside and is formed into a thin wire portion than the other wire portions. Therefore, it is not necessary to change The other component is connected to the front end, and the front end is easy to follow along the cable. The tube has the required flexibility and has the required flexibility: the effect of favorable operation.
